Security Engineer

Lead Security Engineer | £77,000 + Benefits | Hybrid - x1 day per Week onsite (London)

Here at Burns Sheehan, we are working with a growing international business as they look for a Lead Security Engineer to join a small but highly visible security function. This is a hands-on engineering role focused on building and improving security controls across a complex IT estate, rather than sitting purely in monitoring or governance.

The environment is evolving, so this would suit someone comfortable working in a business where not everything is fully mature yet. There’s a strong focus on practical delivery, improving visibility, reducing risk, and implementing controls that genuinely improve day-to-day security operations.

You’ll work closely with infrastructure, engineering, and operational teams, helping shape the security roadmap while remaining technically involved.

What you’ll be doing:

Designing and implementing security controls across infrastructure, identity, endpoint, network, and SaaS environments

Leading initiatives around asset visibility, application discovery, and ownership tracking

Driving zero trust and identity-aware access controls

Improving identity lifecycle management and access governance

Working with SIEM, EDR, and vulnerability tooling to improve detection quality and reduce alert noise

What they’re looking for:

Strong infrastructure or networking background with progression into security engineering

Hands-on experience implementing Zero Trust, SSO, IAM, and security controls from scratch

Experience with Entra ID, SIEM/EDR platforms, vulnerability management, and asset visibility programmes

Good understanding of Microsoft environments, endpoint security, and SaaS-heavy estates

Comfortable operating autonomously in a lean, fast-moving environment where priorities evolve quickly

Sound Interesting? Feel free to Apply and I look forward to your applicaiton !!!
